Planning Your Application
Chapter 4

Using the same addresses for Numeric Displays on different
screens—by using the Current Screen Number to PLC Controller Option
function, you can tell the PLC controller which screen is currently
displayed. The PLC controller could then be programmed to display one
set of values if the first screen is displayed, and a completely different set
of values when the second screen is displayed.
Using the same address to send multiple types of information to the
terminal—by allowing the PLC to use the same address to send multiple
types of information to the PanelView terminal, the Scrolling List object
reduces PLC ladder logic and addressing typically needed to display and
edit large amounts of data.
There are six worksheets to help you plan an application. They include:
Screen Worksheet for Keypad Terminals
Screen Worksheet for Touch Screen Terminals
Object Address List
Discrete I/O Usage Worksheets
Block Transfer I/O Usage Worksheet (2 pages)
PLC Communications Worksheet
Two blank copies of each are included in Appendix C, Sample Worksheets.
Included in this chapter are completed worksheets for a sample application
discussed in this chapter and in Chapter 5, Creating a Sample Application
File. This section describes the steps involved in completing the
worksheets. A discussion of each worksheet follows.
How to Complete the Worksheets
1. Determine the rack numbers you can use for your PanelView
terminal. Although you won’t know your exact PLC I/O address
requirements until you’ve defined all the objects, windows and PLC
controlled options, you do need to know what rack numbers are
available so you can assign PLC addresses.
2. Use the appropriate screen worksheet and draw the objects for your
first screen.
